WATER-ELEVATOR.

SPECIFIGATIN forming part of Letters LE'atent No. 665,210, dated January 1, 1901.

Application tiled April 24, 1900. Serial No. 14,154. (No model.)

and to provide a simple, inexpensive, andefcient device designed for vuse on wells and adapted to be readily operated for raising and lowering a pair of buckets.

A further object of the invention is to provide an apparatus of this character adapted,

to be readily operated to movel the buckets in either direction without necessitating the operators changing his position with relation to the apparatus.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a vertical sectional View of a water-elevator constructed in accordance with this invention. Fig. 2 is a plan View, partly in. section. Fig. 3 is a detail sectional view of a portion of the frame.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a supporting-frame mounted upon a well-curb 2 and provided at opposite sides with suitable journal boxes or bearings 3 for the reception of a horizontal shaft 4, upon which is mounted a large pulley 5. The shaft has its ends reduced to yform journals or gudgeons 6 and to provide shoulders to prevent any longitudinal movement of it, and the pulley is secured to the -shaft by means of a clamping-screw 7 but a key or any other suitable fastening device may be employed for this purpose. A small pulley 8 is fixed to the large pulley 5, preferably by being cast integral with the same, and these pulleys 5 and 8 are provided with peripheral grooves, preferably V-shaped in cross-section, for the reception of an endless operating-rope 9-and a lifting-rope 10. The frame which supports the horizontalshaft may be of any desired construction, and when the apparatus is applied to covered wells it may be secured to the roof or covering of such wells,

The endless operating-rope,which is arranged upon the large pulley, extends from the same to a small pulley or idler 11, journaled on an enlarged end 12 of a lever 13,

and the latter is fulcrunled between its ends in a mortise of a stake 111. The guide-pulley or idler 11 is arranged close to the ground, as clearly illustratedin Fig. 1 of the accompanying drawings, and the upper and lower liights of the endless operating-rope 9 are arranged within convenient reach of the operator, whereby the pulley 5 may be readily rotated in either direction by pulling upon one side or the other of the rope 9.

The lifting-rope, which is arranged on the small pulley 8, is provided at each end with a bucket 15, and by rotating the large pulley 5 the buckets are raised and lowered, as will be readily apparent. The relative size of the pulleys 5 andv S may be varied lo obtain the desired leverage, and it will be apparent that the apparatus may be constructed so that the buckets can be raised and lowered conveniently by a child.

Ilhe'stake or support 1i may be readily driven into the ground the desired distance from the well 16, and the large end 12 of the lever and the guide-pulley or idler 11'have suflicient weight to maintain the endless oper ating-rope taut and provide the proper tension to prevent the rope from slipping, and the lever is adapted to swing upwardand downward and it will enable the operatingrope to yield to the pull of the operator. The Weight of the enlarged end of the lever may be increased by a supplemental weight 17; but this may be omitted, if desired. The lever 13 is provided at intervals with perforations 18 to receive the pivot 19 and to permit the lever to be adjusted.

1t will be seen that the water-elevator is exceedingly simple and inexpensive in construction, that it will enable a pair of buckets or analogous receptacles to be readily raised and lowered and moved in either direction without necessitating the operators changing his position from one side of the well to the other, and that the lifting apparatus may be conveniently employed as an elevator for raising and lowering material and the like at buildings and for similar purposes.

Instead of employing a rope, as illustrated in the accompanying drawings, a cable or any other suitable flexible connection may be used, and the bearings, which are constructed in any suitable manner, are preferably provided with oil-cups, as illustrated in Fig. 3.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claim may he resorted to without departing from the spirit or sacrifcinganyof the ad vantages of this invention.

That is claimed is- A Water-elevator comprising a frame designed to be arranged at the top of a Well, a horizontal shaft journaled in suitable bearings of the frame, the large pulley mounted on the shaft, a small pulley rotating with the large pulley, a hoisting or lifting rope arranged on the small pulley and provided at its ends with buckets, the removable stake designed to be driven into the ground at a point remote from the Well, the approximately horizontal lever provided at intervals with perforations and pivoted to the stake and capable of longitudinal adjustment to move its inner end toward and from the Well, a guidepiilley mounted on the inner end of the lever, a Weight engaging one of the perforations of the lever and arranged at a point between tne stake and the Well, and the endless operating-rope arranged on the large pulley and eX- tending therefrom to the guide-pulley and having both of its High ts arranged at one side of the Well and extending a considerable distance beyond the said well to enable the hoisting or lifting rope to be moved in either direction, said stake being adapted to be readily arranged the desired distance from the well and being capable of heilig changed from one point to another to change the position ot the operating-rope and the said lever being also adapted to be moved longitudinally to vary the length of its inner arm to position the guide-pulley properly With relation to the operating-ropes, substantially as described. ln testimony that We claim the foregoing asour own We have hereto a'l'ixed our signatures in the presence of two witnesses.
